Marquese is making 10 pounds of trail mix from raisins and nuts. raisins cost $3.45 per pound, and nuts cost $7.95 per pound. how many pounds of raisins and how many pounds of nuts should marquese use for the trail mix to cost him $6.96 per pound?

Pounds of raisins = 8.78 pounds

Pounds of nuts =  1.22 pounds

Explanation:

$3.45X + $7.95(10-x) = 10 pounds *$4/pound

$3.45X + 79.50 - 7.95x = $40  

Now simplify the x variables on the left and subtract the dollar amount from the right:

3.45x-7.95x = 40-79.50

-4.5x= -39.50

Divide by negative 4.5 to solve for x

x= 8.78 (rounded)

Remember that x= amount of raisins and (10-x)= pounds of nuts

Pounds of raisins = 8.78 pounds

Pounds of nuts = (10-8.78) = 1.22 pounds

Notice that 8.78+1.22 = 10 pounds, so it all checks out!

the answer is i don't know
